Is the RGB image format supported in dwRectifier, or is only RGBA?
When using the dwRectifier_warp we get the following error.
Driveworks exception thrown: CudaTextureObjectCache::getOrCreateTextureObject, error cudaErrorInvalidChannelDescriptor: invalid channel descriptor

Would it that be the reason?
Thanks in advance.

Hi @sacha ,

RGB is supported. So we need more information to look into it.
What’s the inputImage->prop.format used for the function call? Please also share the full messages of the problem. Thanks.

Hi @VickNV,

the inputImage->prop.format = DW_IMAGE_FORMAT_RGB_UINT8
just by doing a dwImage_copyConvertAsync to RGBA format, it is then working…

Did you mean calling dwRectifier_warp() with the output of dwImage_copyConvertAsync() doesn’t have the issue?

Could you share the full messages of the issue? Could you share the dwImageProperties of dwRectifier_warp() inputImage in both success and failure cases?
